Jetpack Compose.
Jetpack Compose is Android's declarative UI toolkit. Interfaces are composable functions of state, recomposed when that state changes. It replaces XML layouts and the view binding around them, and interoperates with the existing View system in both directions.
Where Jetpack Compose fits on a long engagement.
Compose removes an entire layer of Android work: no XML, no findViewById, no adapter boilerplate for lists. The mental shift is that the UI is derived from state rather than mutated, and teams coming from the View system usually take a few weeks to stop reaching for imperative updates that the framework will simply discard.
The performance characteristic to understand is recomposition scope. State read at the top of a tree recomposes everything beneath it, and the resulting jank looks like a framework problem when it is a state-placement problem. Reading state as far down the tree as possible is the single most useful habit in a Compose codebase.
What an assigned team does with Jetpack Compose.
Migration from XML is incremental by design, and the realistic end state for a large app is years of coexistence. That makes a stated migration policy — which screens move, when, and why — more valuable than a target date nobody will hold.
Because the components and the design system are the same artefact seen from two sides, this work is scoped with design rather than after it, under an outsource ux design agreement covering both.
What we use Jetpack Compose for.
- New screens without the XML layer Features built declaratively inside an existing app, with no rewrite required to start.
- Diagnosing recomposition jank State moved down the tree so recomposition scopes shrink, which is usually the whole fix.
- A design system expressed in code Theming and components defined once, so the app and the design file describe the same thing.
How Jetpack Compose capacity is assigned.
Compose capacity is assigned inside mobile development, normally alongside a designer so the component library and the design system stay one artefact.
